Lightweight and buttery smooth under foot, the new Road N 1 is the perfect choice for a race day PR or tempo workouts. Weve fine tuned the feel by boosting flexibility and adding a full blown rubber forefoot to promote a smooth and quick running sensation giving you the liveliness you need for maximum speed. New 3-D Seamless Print Upper Technology adds lightweight structure and upper integrity. Transfer Dry spacer mesh keeps feet cool and dry. New Dynamic offset-shaped E:MOTIONTM midsole is biomechanically tuned for a mild over pronation running gait. Blown rubber in the forefoot and carbon rubber in the crash pad combine for great cushioning and abrasion resistance. Dynamic Offset: 1 mm at initial contact to 4.5 mm at mid-stance; Heel Stack Height: 19 mm (includes midsole and outsole).
